10.  tall glandular, hairy annual herb occasionally reaching two meters in height  somewhat gangly and thin like an erect weed  narrow, curving, pointed leaves up to a few centimeters in length  flower has four petals which may be so deeply notched that they look like four pairs; generally light purple or pink, with darker veining  fruit is a capsule, 1 to 3 centimeters long TALL, TALL ANNUAL OR PANICLED WILLOW-HERB OR TALL FIREWEED (EPILOBIUM BRACHYCARPUM)

11.  flowers are tiny, pink/white/light-blue, and inconspicuous  very common and highly variable plant  "small and inconspicuous or no withered leaves" at flowering time  moist montane and sub-alpine trails, near ponds, and along irrigation ditches  common to have red stems and leaves in the spring and to return to these colors in the fall HORNEMANN'S WILLOWHERB (EPILOBIUM HORNEMANNII)

12. HAIRY WILLOW-HERB VS. NATIVES  11 native species of Epilobium exist in Colorado  Range in elevation but mostly in wet places  Native flowers smaller/more delicate and less pink Fringed willow-herb (TE) Epilobium ciliatum Epilobium brachycarpum Tall annual willow-herb Marsh willow-herb Epilobium palustre Milkflower willow-herb (TE) Epilobium lactiflorum Talus willow-herb Epilobium clavatum Bog willow-herb (TE) Epilobium leptophyllum

13.  Known in riparian areas of Boulder  Was first identified in the Wonderland and Fourmile Canyon Creeks. Is now found along Boulder and South Boulder Creeks  Not sure how fast it’s spreading, but is definitely a monoculture-forming plant  Extra concern due to 2013 flooding GARDEN LOOSESTRIFE (LYSIMACHIA VULGARIS)
